The book of Prof. Z. gives a new and bright proof to how important is the application of the principles of physiological experiment to the clinical research, and how productive can be the idea of necessity to find out the dynamics of the disease process, which only leads to understanding of the functional state of a sick cell. As simple as this provision is, it still has to be emphasized in view of the fact that clinical thought still remains clenched within the framework of pathological and anatomical notions and has difficulty breaking away from them. Without diminishing the importance of morphological knowledge in the slightest degree, however, every attempt to push the boundaries of clinical investigation towards the application of methods which allow to find out the functional relations should be welcomed.
